I jut bought a MK808b. Everything went ok, I made some minor modifications like turning the screen etc. The final step was to customize the startup animation. I have preapared the gif-s as usual together with the desc.txt. Than I have restarted the MK808b, the animation didn't came up, the operating sistem started but the upper half of my screen is now blank! everything works but I can't see the top of the screen. I made a factory reset, but nothing changed, only wiped out the apps I have installed but things made to root are the same. How to reset everything back to normal?? Please help, Thanx!
